Objective: To evaluate the dose-response relationship between smoking load and cardiopulmonary fitness, as measured with cardiopulmonary exercise testing (CPET), in adult smokers free of respiratory diseases. Methods: After ...

This study compared VO2 peak and cardiopulmonary parameters during the Bruce Protocol (BP) and a cardiopulmonary exercise test (CPX) in 8 diabetic (DG, 55.4 ± 7.0 yrs) and 13 non-diabetic (NDG, 51.5 ± 5.8 yrs) subjects. ...

Spirometry has been used as the main strategy for assessing ventilatory changes related to occupational exposure to particulate matter (OEPM). However, in some cases, as one of its limitations, it may not be sensitive ...

The neuromodulatory effect of NO on glutamatergic transmission has been studied in several brain areas. Our previous single-cell studies suggested that NO facilitates glutamatergic transmission in the nucleus of the solitary ...

In the 1930–1940s Levy and coworkers administered low oxygen tension (thus simulating exposure to an altitude of about 5000 m) while monitoring ECG, in order to demonstrate coronary inadequacy resulting from imbalance ...

INTRODUCTION: The sequelae of COVID-19 have been described as a multisystemic condition, with a great impact on the cardiovascular and pulmonary systems with abnormalities in pulmonary function tests, such as lower diffusing ...

PURPOSE: To analyze the behavior of cardiopulmonary function in postoperative of laparoscopic Nissen fundoplication. METHODS: Thirty-two patients, 13 males (41%) and 19 females (59%), were evaluated. Their age ranged from ...
